Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

changelog scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Changelog Skill

Status: Experimental — uses Claude Code PostToolUse hooks; the hook interface may change in future versions. If hooks don't fire, events can still be logged manually via auto-loop prompts.

Runtime observability changelog that records every change during a development session, so subagents can understand prior context and sessions can be recovered or debugged.


Overview

Automatically, via PostToolUse hooks, the changelog:

  • Records file changes (Write / Edit)
  • Logs test results when tests run (Bash)
  • Records git commits (Bash)
  • Rotates itself when it exceeds 500 lines

Events are stored as append-only JSONL at .director-mode/changelog.jsonl.

/changelog --list-archives  # Show rotated changelogs
/changelog --export log.json
/changelog --archive        # Manually archive current changelog
/changelog --clear          # Clear current changelog

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
